It doesn't seem too fast to me, although I have no basis for comparison. The sprocket has 11 teeth and the winch axle is about 1" in diameter, so if my figuring is correct it should be (initially) reeling in about 1/4" of strap per click of the pawl. That rate increases as more strap gets wound around the axle to maybe 3/8" per click as I'm getting the bow close to full draw. When close to full draw, I quit using the winch and use the jack screw in the press to slowly lengthen the press and get through the end of the draw cycle.Do you feel like it winds too fast?
You can double the strap back like the LCA draw board is to cut the cranking speed in half.
When I have used the boat winches before they seem to wind pretty fast, but you look to probably have a smaller winch.

I already had the necessary tools and material on hand so when I saw the price of the LCA draw board, I figured it was worthwhile to try to cobble together a DIY version. Only cost me a few hours of time...and a few gallons of sweat working in the 100 degree garage.looks like it beats dropping 260 bucks on their version of it. I really need one of these. 2x8 boat winch draw board isn't my favorite.
Can you tell me what the I.D of the square tube is on the bow press.It's no fine work of art, but it'll do.

The pieces that slide inside the press frame are 1.5" square tubing...fits like a glove. I used 3/4" rebar for the bow holder sleeved with a scrap of fuel hose to protect the bow. The winch came from Amazon.
A pair of set screws through the wall of your press tubing or some shim stock could be used to take up the gap.Thanks for the pictures. I made my own press and want to run the LCA drawboard attachment but the I.D on my square tube is 1-3/4". I might have to just make my own
The winch I'm using only ratchets as I'm drawing the bow. To let the bow down, I grab the winch handle with one hand, use the other hand to disengage the pawl, and slowly rotate the handle. I don't know whether or not the LCA draw board has a two-way winch that would ratchet while drawing back and letting down.Mighty Mouse does the lashing winch have a way to draw down the bow using the gears? Do you know if the LCA winch does? If not are you using the handle to draw down with no other control.
