Rid bench flex while reloading


Recommended Posts

So since I've gotten my 650 press and mounted I've noticed an unbelievable flex in the bench. My 550 wasn't a problem but I thought I had supported it pretty well. I have 2x4 framed cross section every 2'. Work bench top is furniture grade oak 3/4". I tried to add additional 4x4 braces where press is but still flexes. I'm thinking the only next option is steel 1/4" plate and frame. Any ideas without breaking the bank. I just don't want to have even more issues if I end up getting a 1050

Post a picture of your bench, and I could be of more help.

However, it sounds like the fix might be in the top. Double up the 3/4 top, or replace with something more solid. My loading bench top is two layers of 3/4" MDF, glued and screwed together, finished in Formica.

Flat faced solid core doors also make great bench tops. Zero flex.

I did the whole top with 2x4s laying edge to edge, then topped with 3/4" ply

I would think 3/4" anything by itself is not enough

if you could get 2 sheets of 3/4 mdf (or ply) under there.. I think you'd fix it. That same thickness can in 2x4s would do it too

I wonder if I could get a small-ish reloading bench, ready-to-assemble, to fit into two large flat rate boxes meant for board games. One box would contain the top, which when put together would get you just about a 2 foot by 2 foot surface area.

The other box would contain the legs, which would be telestrut (just take a closer look at street signs next time) and the steel "aprons" to tie everything together.

This is what telestrut looks like:

The advantage being that the bench would be height adjustable....since the pieces of telestrut are meant to telescope one inside the other and the holes all line up.

Put leveler feet on the bottom.

Maybe an angle iron stretcher or 4, so a plywood shelf could be put across them to hold heavy stuff like bullets to weigh the bench down.

when I built my wooden 2X4 reloading bench about 19 years ago at the base's woodshop, I mortised and tenoned everything. I took a router with a 1/2" round nose bit and plowed a "gutter" all the way around the top about an inch in from the edge. That way brass and bullets just don't go rolling off the top and falling to the floor. They get caught by the gutter first.

getting back on topic....

me? personally? I don't like a material like MDF or particle board for a top which will be under stress or weight. Those kinds of man made materials have this tendency to creep or sag under the load.

I pushed mine against a wall, and attached it to the wall with lag bolts. The wall being on the opposite side of the table of the press, so the flexing/lifting caused by the force on the press handle goes into the wall instead of lifting the table up and down. Even a stiff table will move up and down, (not technically flexing) if it is not somehow anchored to something. Made a huge difference in reliability and quality...no more flipped primers every hundred rounds or so on my 650. There's 2x4 framing under the table & press, where I've anchored the press.

I agree. This one looked like an old horse when I finally threw it away.

I was thinking of making one out of steel when I move. All the houses we've been looking at have nice shops so it'll be anchored to foundation. I've supported it in every way possible but I think you guys are right even oak furniture laminate is not a good surface. I thought about going solid oak but it was double the price. Guess I should of oped in for it

Mine is bolted to the wall on three sides. 2X4 framing with two sheets of 3/4" ply topped off with a kitchen counter top. A 4x4 leg is right underneath the press. And believe it or not it still moves a tiny bit when I run the press. There is a lot of leverage in a press handle.

I have a shelf about 20 inches off the ground the full length of my bench. It tightens up the bottom of the "cube." I presently have about twenty 25# bags of lead shot on the bottom shelf and that does not hurt either. I also do cross members glued and screwed below every metallic press. I use a lot of glue to tighten up the rigidity of the bench, screws and bolts allow movement. I anchor to the studs in the adjacent wall wherever possible with 3.5 inch screws.

I had a hard time seeing your bench. The picture was oversized for me.

I have used once and still have it installed on one of my presses a mounting plate like this to increase rigidity:

You would not necessarily need that plate, but some scrap steel or aluminum integrated into the setup will increase rigidity.

Try a Dillion Strong mount(Stock#22052).

It should spread out the load and raise the height of the loader.

Bench is already too high I thought about it.

It is bolted to studs. Main issue is it top of bench. Going to have to thicken it with another 3/4" piece. Since 12" joists aren't working to stiffen it

Just out of curiosity, how tall is your bench? Mine is 42" and I use a strong mount. I have a tall stool I can sit on, but I like standing when I reload. I am not unusually tall,6-1.

I think mine is like 48" about mid chest level and I'm only 5'8".
