I'm working on a new drop tube and stand. Stand is 14" tall and has a "shelf" on the top. Base is 5 1/2" wide and 8" long Shelf is 5 1/2" wide and 13" long. wood is poplar as that's what I had handy. I have a piece of 3/8" of X .250 ID X 36" long brass tubing ordered from online metals. Also a piece of 1/4" thick X 6" wide X 12" long aluminum plate that's going to be a leveling plate.
My idea is to set the scales ( RCBS Dial o Grain) on the shelf in front of the tube. Drop charge from measure into scales and trickle up if needed. from there a short trip up to the funnel on the drop tube to charge the case. The Belding an Mull measure I use will be on the shelf of the bench along side the stand.
Ive got the stand about done. ( I'm leveling the pad and shelf with clear epoxy now for a dead level surface to work from). Then Drill and fit the 3/8" hole for the tube. I'm polishing the tube off and on and about done there. I have a funnel made that's a little shallower and bigger than the rcbs are. The rails for the tube are 1 1/2" thick on top a 1" space then a 3/4" rail for a 3 1/4 spacing on the tube. I have to decide on the bottom case funnel. A stop for the tube. and a padded finger grip area for lifting it. I'm thinking a 3/8" brass washer soldered to the tube for the stop, or a 3/8" stop collar ( this would be adjustable also). For the case funnel I haven't truly decided much yet. Ill get the pad and shelf leveled with the clear epoxy and a couple coats of oil on it. Then worry about the case funnel.
