RCBS JR Press mount for 2" trailer receiver hitch


Registered Users do not see the above ad.


I want to be able to carry a RCBS JR Press to Virginia next month that can mount to a 2" receiver trailer hitch.

I have seen such over the years at Perry etc but don't remember exactly what was done. Of course the JR has a clearance issue on the bottom to be considered. I would love to see a picture of one of these as well.

I also saw a wood bench mount for a press in a picture years ago and would like to see a picture of what some folks might have done.

I use a pintle plate, about $25. Mount a 2x8 to get it up to chair height (about 28" depending on you vehicle.)and double up the 2x8 at the top for lag bolts.

Trailer Hitch Pintle Hook Mount, 5-1/2" Tall, 6K Tow Ready Pintle Hitch 63056


Could always get some one to weld a 2x2 box beam insted of wood.

Could for certain get some ammunition made on one of these. Nothing unique like what yo ask though.

Actually I have two receiver mounted cargo racks that I have enhanced and added rails about 6" above the racks that are built from 2" heavy angle and expanded metal floors that will hold heavy loads on my receiver hitches. Much heavier than the commercial racks. I have them covered with red and while reflective strips like on 18 wheelers. They can be spotted at 1000 yards. I run one all the time on my Durango as I find people don't seem to want to tailgate me so much haha. I even wired stop/tail/turn LED lights and a center mounted brake light on the rack. Thus when I tap the brakes I have six brake lights come on.

I can place about six 5 gal gas cans on it and chain them in place and secure them with a padlock so they don't disappear while I am in a store. Not real thrilled about carrying gas can inside vehicle !! haha.

I was walking around out in my shop this morning and I hit on a idea. I spotted a router table I forgot I had and it was almost the right height but too light so I got to thinking something along the line of one of them. The more I thought about it the more it seemed to be the way to go.

The idea is cooking and I am thinking of a totally different design. I started and milled out the top section from 3/8" plate before lunch and I have a 2" slot milled in plate with a surface mill that is nice and round at the back of the slot I cut and fits the underside of the RCBS JRS perfectly. I am going to look for at least a 1/4" plate for the base. The top is just big enough to place one of the magnet based parts trays on it to hold primers. Saw them at Harbor Freight. I am going to secure the press to the plate by drilling two holes and tap them with 3/8" tap so I won't have to worry about the usual nuts/lock washers.

Next I have to work out the legs and the problem seems to be holding the legs properly while I tack weld them to the top and the base. I might have to get with a buddy who is a A1 welder and we work well together fabricating things.

Things are going to be jumping around here for next three days so it will be Monday before I get back "on the job". Bottom line is that I think I have thought of a way to make a portable table that I won't have to clamp down and not likely to tip up while FL sizing cases.

I have a 7/8X14 tap and thinking about drilling a hole in the plate behind the tool and tapping it to mount the powder measure. Also thinking of mounting a RCBS primer seater (one of the single models with the cam).

This is portable that you can clamp to table for loading

You could make base using trailer hitch for it.

Very nice, very close to what I am designing.

I figure put a piece of indoor/outdoor rubber backed carpet on table etc and clamp base down with Vise clamps as I have short and long ones.

Many thanks for the info.

I was in a Sears store before Christmas and they had all of their rolling tool chests 50% off. I bought one with 4 drawers (they gave me an additional 10% off for using my Sears card) I bolted two 2x4's to the lip on top (designed to hold a top chest) then screwed a 2x10 across these 2x4's. Bolted my press on one side and my powder measure on the other side of the 2x10. I can lock the wheels when in use, unlock them to roll chest into corner when not in use or up on trailer or into truck if I want to take it somewhere. Not as much room as if mounted on a permanent bench, but all the room I need for what I am doing now.

Well I have been on a roll and taken a lot into consideration on the design I have come up with and to my surprise it has outperformed by best expectations. I have to also mount a 4" vise on it to hold my L E Wilson case trimmer and perhaps a small arbor press.

My base is a piece of 3/8" plate about 20X24 (don't hold me to that) and I machined the legs from 5/8" cold rolled round stock. The legs were precisely cut to 18" and range from 17.999-18.001 in length with 1/4X20 1" deep threaded holes in each end. I measured the handle length on the RCBS and decided to make the top higher so my hand wouldn't be ramming into the bottom plate. Now with the handle in the bottom position it does not protrude beyond the edge of the base plate.

The top plate is about 6X11" and also 3/8" plate with a long 2.015" wide by 6" U cut down the middle and it sports a RCBS JR Press that came out of one of my best friends estate. It is bolted down into threaded holes.

I drilled and tapped extra 7/8X14 holes in the back of the plate to store Lee Universal Decap and a collet bullet puller. Will probably also mount a RCBS primer seater (the one they discontinued about ten years back).

I set it on indoor/outdoor carpet and the cap screw heads sink in and grip the carpet and the rubber bottom will protect a table top as well as provide a rubber grip surface.

I was grinding the corners of the bottom plate to round them off this morning and I set it on a 20 gal steel drum and that set up is perfectly good to load on.

Will also utilize the magnet based parts trays to keep small parts handy like primer rods, Allen wrench etc.

It should work quite well on a pick up tail gate as well or in the back of a SUV.

I will post some pics soon.

With the materials I purchased I have about $60.00 in the base plate and the 20 ft stick of 5/8" cold rolled round stock and the hex head screws and 3/8X16 bolts. I am not going to paint it just yet. Was thinking about getting it powder coated??? Least I think that is what it is called. Of course the stock came with protective coating which turns hands black quickly that I have been trying to wipe off. I estimate I have about 7 hours labor in it now as the legs had to be removed several times to measure their length with my 24" Mitutoyo Caliper.

Just got in from Home Depot where I bought heavy duty handles. After I mount the vise etc I will determine the balance point and put the handles just a tad toward center so I can pick it up and move it without doing a job on fingers/knuckles etc.

OK guys above is a thumbnail of press set up in operation forming 8X60S cases from 30.06 Match cases. Note with the handle in the full down position the 18" columns provide clearance so my hand does not ram into the base.



Here it is in the transport position ready to go into SUV, pickup etc. Note vise is rotated around so it doesn't extend over the side of the base. The silver handles on each side are position off center and towards the front. I found the balance point by sitting bottom plate on a 3/4" piece of all thread and located the balance point and mounted the center of the carry handles there on the theory if I get help to carry it, it won't be wanting to tilt forward or backwards. With the handles being closer to the front the control is much better for a one man carry.



Here is a close up view of the mounting details of the top plate to the 5/8" round stock rods cut to 18" lengths. The three cases shown are Left 30.06 once fired match case, center is neck expansion and right is finished 8x60 trimmed to length. Note bullet puller at back left. Two 7/8X14 threaded holes at back of top plate to screw dies, powder measure etc into when not being used. A close look will reveal 1/4" holes at the back of the plate. As I located the holes on my mill I got to thinking I probably would be OK by placing them closer together so I drilled the center ones. Once I tightened up the 1/4X20 cap screws to about 10 pounds of torque I knew using the close spacing was going to be just fine.



This is the rig tilted up. Note the exposed heads of the 1/4X20 cap head screws protruding from base of plate. The cartridge case necks show the indents in the carpet panels. The panels have a rubber bottom. The mount does not move. Note the FL size die in top does not include the expander ball. I decap with a Lee Universal Decapper and expand with a Humpy Button which is a expander that clamps into a bullet puller collet and the neck is expanded outwards in a down motion which allows for many more reloads without sustaining neck stretch.

Now more info on the assembly:

Bottom plate 3/8" 19X23 3/8". I did not spec it this way. It was a drop from the steel supplier and I just told them I needed 3/8" plate in the 2X2' range and that was first one they pulled up on their list and I took it. I think I gave 25.00 for it.

The top plate is 3/8" and is 5"X 10 13/16". Again it was a drop I had in my shop I found. If I was going to go and get a full 4X8 sheet of 3/8" plate cut up I would spec it about 10"X 12" so I could drill some more 7/8X14 holes for this and that.

The rods as indicated are 5/8" cold rolled and cut on lathe to right on 18" and measured with my Mitutoyo Caliper. A 20 ft stick of it was like 27.00 and change.

I located the tool so the round portion of the underside of the RCBS is directly over the center of the plate so when handle is pushed downwards force is applied vertically to the lower plate and screw heads sink into the carpet and everything grips nicely. At some point I will probably mount a RCBS single primer seater they discontinued about ten years back.

Other nice things is I like to load standing up and the location of the ram at the top of the stroke is right in front of my face. I am 5'9" and the top of the tool is about eye height for me.

I estimate it weighs about 60 lbs and the addition of the metal handles makes for much easier lifting by myself.

I do not foresee the need for a hold down clamp.

I mounted the vise for ease of holding the Wilson trimmer, swivel around out of the way for transport and when rotated to right side will hold a rifle butt (protected by heavy leather belting) to be secured while cleaning the rifle.
